These materials are intended to provide meaningful experience in electronic motor control for students of modern technology. The topics included provide exposure to basic principles of motor control, SCR controls for various types of motors, and an introduction to digital controls. The materials are presented in an action-oriented format combining many of the features normally found in a textbook with those usually associated with a laboratory manual.

This manual, along with the others in the Electromechanical Technology Series, is the result of six years of research and development by TERC, a national nonprofit, public service corporation with headquarters in Cambridge, Massachusetts. It has undergone a number of revisions as a direct result of experience gained with students in technical schools and community colleges throughout the country.
